Types of licensees - a
description of the types of radioactive material licensees in
North Dakota

There are many types of users of
radioactive materials within North Dakota. Licensee categories
are listed below:

Unsealed radiopharmaceuticals or the
radiation from sealed sources administered to patients for
diagnostic or therapeutic purposes. Most hospitals and some major
clinics have nuclear medicine departments. Some clinics and
certain private physicians may also be licensed to use
radioactive materials for only diagnostic procedures.

Unsealed radiopharmaceuticals or the
radiation from sealed sources administered to patients for
diagnostic purposes from a mobile unit instead of a fixed
facility. This type of license is similar to Medical license but
is smaller in scope, while performing at various temporary
locations.

Small sealed radioactive sources used in
permanently mounted test equipment to measure the density of
material within a pipe or the level of material in a vessel.
These are used in power plants and other industrial applications.

Radioactive sources used in underground
well logging applications at various locations. Types of well
logging include: Gamma Ray, Spectral Gamma Ray, Radioactive
Tracer, Density Logs, Neutron Logs, Pulsed Decay Time and Induced
Spectrometry. The information produced during logging can be used
to determine stratigraphic profiles, and also the
porosity/density of the formation.

Small sealed radioactive sources are used
in portable test equipment to measure moisture and/or density of
construction materials, road beds, roofing, or agricultural land.
The gauges are susceptible to theft and damage by road
construction equipment. These are used by government and industry
at various construction sites.

Small sealed radioactive sources are used
in portable test equipment to measure lead content, density of
materials and thickness of pipe wall. The gauges are also
susceptible to theft and damage by heavy equipment.

The use of gamma radiation from sealed
sources to irradiate materials such as blood and blood products
to prevent engraftment and proliferation of lymphocytes capable
of mounting an immune response against the recipient.
Irradiators may also be used to calibrate dosimeters. These
devices are used at blood banks, calibration facilities and
universities.
